Abstract: | A classification theorem for voting rules on a smooth choice space W of dimension w is presented. It is shown that, for any non-collegial voting rule, σ, there exist integers v *(σ), w *(σ) (with v *(σ)<w *(σ)) such that - structurally stable σ-voting cycles may always be constructed when w ? v *(σ) + 1
- a structurally stable σ-core (or voting equilibrium) may be constructed when w ? v *(σ) ? 1
Finally, it is shown that for an anonymous q-rule, a structurally stable core exists in dimension \(\frac{{n - 2}}{{n - q}}\) , where n is the cardinality of the society. |
